White solid, light yellow transparent liquid when melting

This product has very good lubricity, weather resistance, transparency, no sulfide pollution, no oozing. Its lubricity is good in organotin, thermal stability is relatively low in organotin, and has a preliminary color, used in conjunction with smooth organotin and barium-cadmium soap stabilizers and has a coordinated effect.

This product is mainly used for food, pharmaceutical packaging used in the processing of PVC flexible film, hose. Also used as a lubricant for rigid transparent food packaging materials. Also used as catalyst for medical silicone rubber, paint drying agent.

Light yellow transparent liquid, internationally recognized non-toxic organotin stabilizer. This product has very good lubricity, weather resistance, transparency and compatibility, no sulfide pollution, no exudation. Its lubricity is good among organic tin. But its thermal stability is low among organic stannums, and it has preliminary color.

It is suitable for use with thiol-type organotin or with cadmium barium soap stabilizers with synergistic effect.

This product is mainly used in the processing of PVC flexible film and hose used for food and drug packaging. It is also used as a lubricant for rigid transparent food packaging materials, with a dosage of 1.5 mass parts or less. Also used as catalyst for medical silicone rubber.
